ORIGIN OF MADAGASCAR'S FRESHWATER FISHES

Following the publication of several phylogenetic studies investigating the origin of the highly endemic Malagasy freshwater fish fauna and the biogeography of Gondwana. We have expanded these phylogenetic studies with other malagasy freshwater groups to examine, on a case-by-case basis (e.g., Bedotiidae [rainbowfishes], Cichlidae), the evidence for a vicariant versus dispersal origin for all of Madagascar's freshwater fish clades using both phylogenetic pattern and divergence time estimates.
